gstat packageA class containing input and output maps generated through the process of geostatistical mapping. Object of this class can be directly visualized in Google Earth by using the plotKML-method.
variable:object of class "character"; variable name
observed:object of class "SpatialPointsDataFrame" (must be 2D); see sp::SpatialPointsDataFrame
regModel.summary:contains the summary of the regression model
vgmModel:object of class "data.frame"; contains the variogram parameters passed from gstat
predicted:object of class "SpatialPixelsDataFrame"; see sp::SpatialPixelsDataFrame
validation:object of class "SpatialPointsDataFrame" containing results of validation
signature(x = "SpatialPredictions"): spatial predictions, regression model (observed vs predicted), original variogram and variogram for residuals
signature(obj = "SpatialPredictions"): plots all objects in Google Earth
signature(obj = "SpatialPredictions"): summarize object by showing the mapping accuracy (cross-validation) and the amount of variation explained by the model
